安卓 java.lang.IllegalArgumentException : Invalid Transition types

Question

最近我遇到了 java.lang.IllegalArgumentException: Invalid Transition types。 此异常发生在 android api 19 上，并且在我将 android 构建工具和支持库更新到版本 27 后出现。

有人知道 KitKat 转换有什么变化吗？

    Fragment fragment = new  Fragment();
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        Transition transition = new AutoTransition();
        fragment.setSharedElementEnterTransition(transition);
    }

    String backStateName = fragment.getClass().getName();
    FragmentManager manager = getFragmentManager();
    FragmentTransaction ft = manager.beginTransaction();
    ft.addSharedElement(view, "TransitionView");
    ft.replace(R.id.mainActivity_container, fragment, backStateName);
    ft.addToBackStack(backStateName);
    ft.commit();

完全异常:

更新

从 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) 更改为 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) 之后> 我没有异常(exception)。

您正在混合来自 androidx(支持库)和平台的转换。 例如:

import androidx.transition.AutoTransition;
import android.transition.Fade;

(注意缺少的“x”)

将其更改为仅使用支持库，如下所示:

import androidx.transition.AutoTransition;
import androidx.transition.Fade;
